With it's patented built-in string cutter, the Auto Trim tuning machines are solid, reliable, attractive, unique, and may be the best guitar upgrade available to improve ease of use.
Once installed these things are a snap to use. Simply feed the string through the tuning post where marked, lock the string in place with a sufficiently sized thumb-wheel, and turn the tuning key as usual. Here's where you'll fall in love with these unique tuners... as you bring the string into tune, the excess string is automatically clipped off with the built-in hardened steel wire cutter. The days of impaling your fingers with short guitar wires are gone forever!
With less extra string wrapped around the post, you'll stay in tune more consistently. The 18:1 gear ratio is perfect for smooth operation and precise tuning.
This set of six tuning machines is intended for guitars, such as Les Paul and Paul Reed Smith (PRS), with three tuning keys on either side of the headstock. If you've never installed tuning machines before, you should consider having a qualified tech do the job. See below for measurement specifications.
1) The screw-hole on these tuning machines is not offset (see the Top-View image, above).
2) Auto Trim tuners will accommodate a string up to about 0.65".
